Introduction

Python is a high-level programming language that can be used to develop web and desktop applications. Python offers a variety of tools and features that make it easy to write efficient code. One of the most useful features in Python is its logical operators. These operators are used to combine different expressions and values to create more complex conditions. In this article, we will look at the 10 logical operators available in Python.

What are Logical Operators?

Logical operators are special symbols in Python that are used to combine Boolean expressions. These expressions can be either True or False. There are 3 logical operators in Python: AND, OR, and NOT. Each of these operators can be used to create complex conditions that depend on multiple variables.

The AND Operator

The AND operator returns True if both of its operands are True. Otherwise, it returns False. The following table summarizes the behavior of the AND operator:

x y x AND y
True True True
True False False
False True False
False False False

Example:

x = 5
y = 10
if x > 0 and y < 20:
    print(Both conditions are true)
Output: Both conditions are true

The OR Operator

The OR operator returns True if at least one of its operands is True. Otherwise, it returns False. The following table summarizes the behavior of the OR operator:

x y x OR y
True True True
True False True
False True True
False False False

Example:

x = 5
y = 10
if x > 0 or y > 20:
    print(At least one condition is true)
Output: At least one condition is true

The NOT Operator

The NOT operator is used to reverse the logical value of an expression. If the expression is True, NOT returns False. If the expression is False, NOT returns True.

Example:

x = True
if not x:
    print(x is false)
else:
    print(x is true)
Output: x is false

The IS Operator

The IS operator compares two variables and returns True if they point to the same object. Otherwise, it returns False.

Example:

x = [1, 2, 3]
y = [1, 2, 3]
z = x
if x is y:
    print(x and y point to the same object)
elif x is z:
    print(x and z point to the same object)
else:
    print(x and y do not point to the same object)
Output: x and z point to the same object

The IN Operator

The IN operator is used to check if a value is present in a sequence such as a list or a tuple. It returns True if the value is present in the sequence. Otherwise, it returns False.

Example:

x = [1, 2, 3]
if 2 in x:
    print(2 is present in x)
else:
    print(2 is not present in x)
Output: 2 is present in x

The NOT IN Operator

The NOT IN operator is used to check if a value is not present in a sequence. It returns True if the value is not present in the sequence. Otherwise, it returns False.

Example:

x = [1, 2, 3]
if 4 not in x:
    print(4 is not present in x)
else:
    print(4 is present in x)
Output: 4 is not present in x

The <= Operator

The <= operator is used to check if one value is less than or equal to another value. It returns True if the first value is less than or equal to the second value. Otherwise, it returns False.

Example:

x = 5
y = 10
if x <= y:
    print(x is less than or equal to y)
else:
    print(x is greater than y)
Output: x is less than or equal to y

The >= Operator

The >= operator is used to check if one value is greater than or equal to another value. It returns True if the first value is greater than or equal to the second value. Otherwise, it returns False.

Example:

x = 5
y = 10
if y >= x:
    print(y is greater than or equal to x)
else:
    print(y is less than x)
Output: y is greater than or equal to x

The < Operator

The < operator is used to check if one value is less than another value. It returns True if the first value is less than the second value. Otherwise, it returns False.

Example:

x = 5
y = 10
if x < y:
    print(x is less than y)
else:
    print(x is greater than or equal to y)
Output: x is less than y

The > Operator

The > operator is used to check if one value is greater than another value. It returns True if the first value is greater than the second value. Otherwise, it returns False.

Example:

x = 5
y = 10
if y > x:
    print(y is greater than x)
else:
    print(y is less than or equal to x)
Output: y is greater than x

Python is a popular programming language that is widely used for various applications such as web development, data analysis, artificial intelligence, and more. One of the essential concepts in Python programming is logical operators, which are used to perform logical operations on variables or values. Here are the top ten logical operators in Python that you need to know:

  1. AND operator: This operator returns True if both operands are True, and False otherwise.
  2. OR operator: This operator returns True if at least one of the operands is True, and False otherwise.
  3. NOT operator: This operator returns the opposite boolean value of the operand.
  4. == operator: This operator checks if two operands are equal, and returns True or False accordingly.
  5. != operator: This operator checks if two operands are not equal, and returns True or False accordingly.
  6. > operator: This operator checks if the left operand is greater than the right operand, and returns True or False accordingly.
  7. < operator: This operator checks if the left operand is less than the right operand, and returns True or False accordingly.
  8. >= operator: This operator checks if the left operand is greater than or equal to the right operand, and returns True or False accordingly.
  9. <= operator: This operator checks if the left operand is less than or equal to the right operand, and returns True or False accordingly.
  10. in operator: This operator checks if a value exists in a sequence, and returns True or False accordingly.

People also ask:

  • What are logical operators in Python?
  • Logical operators are used to perform logical operations on variables or values in Python. The most common logical operators are AND, OR, and NOT.

  • What is the difference between AND and OR operator in Python?
  • The AND operator returns True if both operands are True, while the OR operator returns True if at least one of the operands is True.

  • How do you use logical operators in Python?
  • You can use logical operators by combining boolean values, variables, or expressions using the AND, OR, and NOT keywords. For example, you can write if x > 0 and y < 10 to check if both conditions are True.

  • What is the NOT operator in Python?
  • The NOT operator returns the opposite boolean value of the operand. For example, if a variable x is True, then not x will be False.

  • What is the difference between == and != operators in Python?
  • The == operator checks if two operands are equal, while the != operator checks if two operands are not equal.
